The health benefits of walking and cycling outweigh the negative effects on health of air pollution, even in cities with high levels of air pollution, according to a study led by researchers from the Centre for Diet and Activity Research (CEDAR) and Medical Research Council Epidemiology Unit at the University of Cambridge. This new evidence strengthens the case for supporting cycling even in polluted cities – an effort that in turn can help reduce vehicle emissions.
The writer Nan Shepherd (1893-1981), who was quietly acclaimed in her lifetime, is the face of a new Royal Bank of Scotland bank note. One of Shepherd’s staunchest supporters is Robert Macfarlane (Faculty of English), who wrote the introduction to her book about the Cairngorms.
Hugh Hunt (Department of Engineering) discusses the mechanism that makes Big Ben chime, and why it needs repairing.
A new technique that allows embryos to develop in vitro beyond the implantation stage (when the embryo would normally implant into the womb) has been developed by scientists at the University of Cambridge allowing them to analyse for the first time key stages of human embryo development up to 13 days after fertilisation. The technique could open up new avenues of research aimed at helping improve the chances of success of IVF.
A genetic variation associated with obesity and appetite in Labrador retrievers – the UK and US’s favourite dog breed – has been identified by scientists at the University of Cambridge. The finding may explain why Labrador retrievers are more likely to become obese than dogs of other breeds.
An international collaboration of researchers has identified five new gene regions that increase a woman’s risk of developing endometrial cancer, one of the most common cancers to affect women, taking the number of known gene regions associated with the disease to nine.
Species of single-celled algae use whip-like appendages called flagella to coordinate their movements and achieve a remarkable diversity of swimming gaits.
Researchers have built a nano-engine that could form the basis for future applications in nano-robotics, including robots small enough to enter living cells.
Three Earth-sized planets have been discovered orbiting a dim and cool star, and may be the best place to search for life beyond the Solar System.
